Often when we cry we feel embarrassed and try to suppress the tears. Or when we are in the presence of someone who’s crying we are inclined to say “Oh, don’t cry, it’s going to be ok.”
Recently we learned something fascinating: human emotional tears contain Serotonin which is a natural anti-depressant. So, when something very sad happens to you, like the passing of your cat or another loved one, don’t hold back the tears, let them flow. Your grief or sorrow will ease; peace and understanding will come.
Here we excerpt a paragraph about human tears and Serotonin from the book “The Blessing of Tears,” by Julie Sheldon.
“In 1994 the findings of a study of the chemical composition of different types of tears was published ( X.D. Martin and M.C. Brennan “Serotonin in human tears” European Journal of Ophthalmology 4(3), 159-69. Serotonin is a neurotransmitter. Recently developed antidepressant drugs such as Prozac aim to increase the amount of Serotonin in the brain. The study compared the amount of reflex tears and emotional tears, and relatively huge amounts of Serotonin was found in emotional tears. This happens because when emotion is experienced, the hypothalamus in the brain releases several neurotransmitters, including serotonin. In emotional tears, Serotonin is the messenger to boost the volume of production of tears from the lachrymal sac.”
